This liquid liner is easy to apply and imparts rich color with just one stroke. Based on the name, you can bet this is shiny, but several shades offer a low-wattage gleam that can be a fun way to enliven evening eye makeup. Avoid the shades with obvious chunks of glitter; not only do they look odd when applied, but also the glitter doesn’t stay in place all that well (and getting glitter in your eyes isn’t fun).

Although Diamond Liner requires several seconds to set, once it does, you can enjoy worry-free, budge-proof wear (unless you choose one of the glittery shades). On balance, this is a good option and a fun departure from standard black or brown liquid liners. Important note: This eyeliner is extremely tenacious and VERY difficult to remove, so be careful to not rub or tug at your lash line as you work to get this off. A cotton swab dipped in baby oil works best.

Brand Overview

Quo At-A-Glance

Strengths: Inexpensive; testers are available for every product; two superb foundations, including one with reliable sunscreen; notable eyeshadows, powder blush, and cream blush; wonderful lipsticks and lip liner; the best makeup brushes available at Canadian drugstores.

This relatively small but comprehensive makeup line is sold exclusively at Shoppers Drug Mart in Canada, and is one of their star performers among a backdrop of other name-brand drugstore product lines. The impetus behind this simple but elegantly packaged line was the need to bring makeup artist–quality cosmetics into a mainstream drugstore. As heroic a claim as that may be, the truth is that there have always been superior makeup formulations at the drugstore—in fact, some of those products have set the standards that the rest of the industry tries to keep up with.

Despite their unconvincing excuse for launching yet another cosmetics line, many of Quo's products have velvety, smooth textures, even application, and a pleasing mix of classic and contemporary shades, including neutral-toned foundations. As was the case when we reviewed this line a few years ago, the standout products are the powder eyeshadows and the makeup brushes; however, the lipsticks and lip liners are also worth your attention. A significant improvement from my last visit is that now the Quo displays feature testers for every product, and the staff at Shoppers Drug Mart encourages you to use them! We wish more drugstore cosmetic lines would incorporate this feature, but for now, this is another area where Quo really stands out, and it deserves serious consideration by Canadian residents and visitors alike.

Of course, not everything Quo offers is remarkable and, if anything, their expanded roster of products seems more gimmicky than innovative, although some of the newer items are outstanding and, given the new testers, now you can try before you buy. The concealer category is the weakest, followed by the powders, which, with one exception, aren't keeping pace with advances in this area, especially compared with the preferred options from L'Oreal and Revlon (often sold right next to Quo).
